H1b Applicant for admission who is no longer working for the original petitioner

[prasadbabu]

Hi,

I am planning to travel INDIA in between May/June-17 and will be back by end of July 2017.

I have valid VISA from Sept-14 to Sept-17 with my original petitioner ,I have changed my original petitioner and I have valid new H-1B approval I-797 notice from my NEW petitioner from May-16 to April-19.

In this case ,Can i travel back to USA with out going for the stamping ?

Can you please review my case and suggest.

Thanks,
PR
